01 Aircraft sheet metal overview

Aircraft sheet metal refers to the shaping of metal sheets into various parts required for aircraft through shearing, cutting, folding, hammering, welding, etc. It is an indispensable part of the aircraft manufacturing process. Aircraft metal is of great significance because many parts required for aircraft are made of metal, such as fuselage shells, wings, air intakes, etc. Therefore, it is very necessary to master aircraft sheet metal related knowledge.

In the aviation field, sheet metal processing has important applications and is used to manufacture aircraft structures and aerospace components. The following are some key points for mastering sheet metal processing technology in the aerospace field:

1. High-strength materials: The aviation field has very high requirements for the strength and lightweight of materials. Therefore, high-strength metal materials, such as aluminum alloys, titanium alloys and composite materials, are often used in sheet metal processing. These materials provide high strength and stiffness while being relatively lightweight, helping to improve aircraft performance and fuel efficiency.

2. Complex curved surface components: The aircraft has a complex shape and requires a large number of curved surface components. Sheet metal processing technology can manufacture complex curved components through bending, stamping, cutting and other processes to meet the aerodynamic performance and structural requirements of the aircraft.

3. CNC machining technology: The aviation field has very high requirements on the accuracy and quality of sheet metal components. CNC processing technology is widely used in sheet metal processing in the aviation field, such as CNC punch machines, CNC bending machines, CNC laser cutting machines, etc. These equipment have the characteristics of high precision, high efficiency and good repeatability, and can meet the precise requirements of components in the aviation field.

4.Automated production line: The aviation field has a large demand for large quantities of sheet metal components, so automated production lines are very important in the aviation field. Automated production lines can realize processes such as automatic feeding, automatic stamping, automatic bending and automatic assembly, improving production efficiency and product quality.

5.Quality control and testing: The aviation field has strict quality control requirements for sheet metal components. By using advanced inspection technologies, such as three-dimensional coordinate measurement, optical scanning, etc., precise dimensional measurement and shape inspection of sheet metal components can be carried out to ensure that they meet design requirements and standards.

6.Repairs and Maintenance: Aircraft may be damaged or worn during use and require repairs and maintenance. Sheet metal processing technology plays an important role in the repair and maintenance of aircraft. It can restore the integrity and performance of the aircraft by repairing or replacing damaged sheet metal components.

The world of sheet metal processing in the aerospace sector is highly technically demanding and challenging, requiring precision equipment, advanced materials and a high level of process control. With the continuous advancement of science and technology, sheet metal processing technology will continue to develop in the aviation field, providing more efficient and reliable solutions for the design, manufacturing and maintenance of aircraft.

02 Aircraft sheet metal materials

      A wide variety of materials are used to make aircraft sheet metal parts, depending on the specific application and requirements. Here are some common aircraft sheet metal part materials:

       1.Aluminum alloy: Aluminum alloy is one of the most commonly used aircraft sheet metal materials and has a good strength-to-weight ratio. Commonly used aviation grade aluminum alloys include 2024-T3, 6061-T6 and 7075-T6. They have excellent rigidity and corrosion resistance and are suitable for use in aircraft structures and skins.

       2.Titanium Alloys: Titanium alloys offer excellent strength, stiffness, and corrosion resistance while being relatively lightweight. They are commonly used in the manufacture of high-temperature components, engine covers and aerospace equipment. Common aviation grade titanium alloys include Ti-6Al-4V and Ti-6Al-2Sn-4Zr-2Mo.

       3.Stainless Steel: Stainless steel is used in aircraft sheet metal manufacturing for parts requiring high strength and corrosion resistance. Commonly used aviation grade stainless steels include 304 and 316.

     4.Composite materials: Composite materials are composed of fiber reinforced materials (such as carbon fiber, glass fiber) and matrix materials (such as epoxy resin). Composite materials have high strength, lightweight and good corrosion resistance. They are commonly used in the manufacture of components such as wing panels, tails and canopies of aircraft.

     5.High-temperature alloys: High-temperature alloys are used to make parts that need to withstand high-temperature and high-pressure environments, such as turbine engine blades and combustion chambers. Common high-temperature alloys include nickel-based alloys and cobalt-based alloys.

In addition to the above materials, there are many other special materials used to manufacture specific aircraft sheet metal parts, such as magnesium alloys, composite laminates, etc. When selecting materials, factors such as strength, weight, corrosion resistance, high temperature resistance and manufacturing cost need to be comprehensively considered to meet the design requirements and performance needs of the aircraft.

03 Sheet Metal of Industrial Man

        Introducing foreign advanced technology and producing ultra-high standards and ultra-high quality. With 2,000 tons of stamping equipment, Industrial Man are not only committed to the stamping and molding of large parts such as outer covers of new energy vehicles, battery packs of electric vehicles, and casings of energy storage equipment; they are also useful in aviation, photovoltaics, home appliances, and mobile phones. to the stamping and forming process of continuous high-volume parts. In the world of aircraft sheet metal, stamping is a relatively traditional equipment. Stamping machines of different tonnages are used according to the size of hardware parts. Good reputation wins more trust. Industrial people produce more than one million pieces of hardware parts in batches, and the production using continuous stamping molds has already exceeded 100,000 pieces!
